Abstract
It has been shown both theoretically and experimentally that as the tempering temperature of quenched low-carbon steels increases up 600–650°C, the values of induction on the asymmetric “coercive return–magnetization” cycle decrease monotonically at fixed, proportional to the coercive force, values of magnetic field. This effect is associated with a transition from structures with a uniaxial magnetic anisotropy (after quenching) to structures with three easy-magnetization axes (after hightemperature tempering). Within the model of prevailing 180° displacements, numerical estimates have been produced for the magnetic parameters of the “coercive return–magnetization” cycle in these magnetic structures. The estimates are in a good agreement with experimental data. It is shown that induction resulting from the inversion (polarity switching) of coercive field exhibits a structural sensitivity that is similar to that demonstrated by coercive-return magnetization and is therefore a promising parameter for magnetic structural analysis. It has been demonstrated that the proposed parameter can be measured locally using the DIUS-1.15M mobile hardware-software system.
